UNITED STATES HENRY W. PUTNAM, OF BENNINGTON, VERMONT.

IMPROVEMENT IN MACHINES FOR BENDING WIRE FASTENINGS FOR BOTTLE-STOPPERS.

Specification forming part of Letters Patent No; 115,102, dated May 23,1871.

To all whom it may concern:

Be it known that I, HENRY W. PUTNAM, of Bennington, in the county ofBennington and State of Vermont, have invented an Improvement inMachines for Bending Wire Fastening for Bottle-Stoppers; and thefollowing is declared to be a correct description thereof.

This invention is for bending up the wire and forming fastenin gs forbottle-stoppers, such as shown in Letters Patent granted to me March 15,1859 and the present improvement relates to the construction andarrangement of the bending-dies, whereby the operations are performedsuccessively and with great accuracy.

In the drawing, Figure 1 is a sectional plan, showing the bending-diesas closed. Fig. 2 is a sectional elevation at the line 00 w, and Fig. 3is a similar View at the line 3 y.

The wire a is fed into the machine by a pair of rollers, a, and isarrested by the adjustable stop I), and cut off by the movable shears0', shown also in Fig. 4, the lever-arm c of the shear 0 being operatedby a cam, 2, upon the main shaft d, that is driven by competent power.By moving the shear and guide different lengths of wire may be cut off.The rollers a are actuated by connecting-gears 3, and a belt or gearingat 4, to the shaft d.

The feed-rollers should be made with a sectional elastic surface, toclamp the wire when the feed takes place, the rollers slipping upon thewire at other times.

The dies 6, f, and g bend the bow into the compound curved form shown inFig. 1, the die fbeing first brought up against the wire to press thesame into the stationary die e and make the central bond 5. Then thetwopart or forked die 9 is brought up to bend back the wire against theedges of c and form the two bends 6 6. The inner faces of the forked dieg are grooved to contain the wire, so that a two-part pusher, k, actingup through openings in the bed I, may bend up the wire around the endsof the fork g and at the sides of the die 6, to make the bends 7 7 inthe fastening. (See perspective view, Fig. 5.) The clamping-dies m m arenow forced against the wire to bent it near the ends by forcing saidwire into recesses at the sides of the die 0, and then the two-partpresser n is forced down to complete the bends 8 S in the fastening andform the projecting pins or hinges, upon which the fastening swings whenattached to the bottle by a neck-band or wire.

The dies, punches, and presser before mentioned are moved in the ordernamed, and to effect that motion properly-shaped cams are employed. Ihave shown cams, slides, and other devices that are adapted to givingthese movements, but do not limit myself to the precise constructionshown.

The dies f and g are shown as moved at the right time by the cams f andg acting on the levers o and 0 and these cams may either be grooved, orelse the curved bars 13 14 be employed to act upon the cross-pins at theends of the levers 0 0, to return the dies to a normal position.

From the forked die 9 spring-fingers a" project, to draw the fastenerofl the die 6 upon its return movement, so that said fastening may fallthrough a hole in the bed Z. The two-part pusher k is moved by a slideand toe, k, and cam s. The clamping-dies m are mounted in slides on thebed I, and acted upon by wedges m, that are lifted up through openingsin the bed I, by the cross-head t and links t, to cranks upon the endsof the shaft d, the return-spring 19 being used to draw the side clampsm back. The presser n is operated by a cam, n, and lifted by the spring20.

The parts being properly timed, the dies bend up and complete one of thesaid bottlefastenings each revolution of the machine.

The die 0 should be made in two parts, so that the upper part may beraised or lowered, to adapt the machine to fastenings with long or shortsides for bottles of diiferent-shaped necks, the parts being kept apartby keys or wedges; and the clamping-dies m are also made similarlymovable to act properly against the sides of said die 6.

It is preferable to have the hole in the die e for the first bend topass entirely through, to facilitate cleaning or removal of brokenpieces of wire; and I remark that the die 6 might be moved, ifpreferred, instead of being stationary.

I claim as my invention The dies 0 f g, pusher k, clamping-dies m, andpresser n, arranged and acting substantially as set forth, for bendingup wire fastening's for bottles, as set, forth.

Signed by me this 30th day of March, A. D.
